BLIND OR SHUTTER HINGE.

SPECIFICATION forming part of Letters Patent N o. 744,232, dated November 1,7', 1903.

Application filed August 10, 1903. Serial No. 168,877. (No model) To all whom it may concer-n:

Be it known that I, CHARLES PUEEINGTON,

a citizen of the United States, residing in the' vof which the following is a specification.

My invention relates to improvements in blind and shutter hinges; and the objects of my improvement are simplicity and economy in construction with eiiiciency in operation.

In the accompanying drawings, Figure l is a side elevation of my hinge with the leaf member turned so as to stand longitudinally to the companion member of the hinge. Fig. 2 is a plan view of the same with the two members of the hinge separated from each other. Fig. 3 is a central longitudinal section of the pintle member on the line 0c of Fig. 2, the pintle and plunger being shown in elevation. Fig. 4L is a plan view of the pintle member with the upper half-socket removed. Fig. 5 is a transverse section on the line y y of Fig. 1.

A designates the leaf member having a platelike body with screw-holes 6 for securingit to a blind or shutter and a perforated hub or knuckle 7 for connecting it with the pintle member,the opening through the said knuckle being of an irregular form to correspond with the form of the part of the pintle to which it is tted.

The pintle member B consists of two halfsockets 8 9, a pintle 10, plunger 11, and-spring 12. The half-sockets are each mainly in the form of a semicircular shell containing spring and plunger recesses, with pintle-lugs 13 at their outer ends, the half-socket 8 having a perforated lug 14 at its inner end and holdingprongs 15 toward its outer end. The halfsocket 9 has a lug 1G and rivet 17 at its inner end to receive the perforated lug 14 of the half-socket 8 and notches 28 on each side toward the outer end for receiving the prongs 15 of the said half-socket 8, whereby these interlocking devices may hold the two halfsockets together by heading downthe rivet 17 and bending or olinching the holdingprongs inwardly a little from the position shown in Fig. 5. The exterior of the two half-sockets is-preferably screw-threaded, as

shown, in order that the pintle member of the-hinge may be secured to the window-casing by boring a hole therein and screwing the said pintle member into the casing. The pintle 10 has two short bearing portions 1S, that are journaled in the pintle-lugs 13, and between the said portions and lugs is the holding-plate, with three holding-faces 19, 20, and 19 for coactin g with the end face of the springpressed plunger 11. The upper end 10 of the Ipintle is of an irregular form flattened on one side and rounded on the other, as best shown in Fig. 2, the opening in the knuckle 7 being of a corresponding form, whereby the pintle will necessarily ,turn with the leaf member ofthe hinge and whereby it will be ilnpossible to put the leaf member on the pintle in any other than the proper position. The leaf member may, however, be put on the said pintle either side up for use as either a right or a left hand hinge.

The plunger 11 consists of a flattened head 11, disk-shaped iiange 21, and stem 22 for extending into the coils of the spiral spring 12, which spring lies within the half-sockets with one end abutting the flange 21 and its other end abutting the end wall of the socket.

That face of the holding-plate of the pintle which is opposite the face 2O is not made use ofv after the blinds or shutters are hung on theirhinges. This face is made a little closer to the axis of the pintle than any of the other faces. The parts are constructed and assembled with reference to having the spring under a good holding tension at all times, and therefore for convenience of assembling the parts the pintle may be turned into a position to bring the holding-face that is opposite the face 2O directly in front of the end'of the plunger 11. Vhen the plunger and spring are forced into their position between the half-sockets, the parts may be then secured together in the manner before described. IVhen the pintle member is screwed into the casing, the several parts will be securely held y IOO held in its fully open or closed position whenever the plunger presses squarely against the faces 19 and half-way open when it presses against the face 20. rlllese faces may bc slanted more or less to vary somewhat the position of the blind when closed or opened, and, if desired, a notch 23 may be made in the end of the plungerll to engage the holding-plate by its corners between the faces 19 and 20, and thus give other locking positions for the blind. f

By my improvement a simple and inexpensive loose-joint hinge is produced and one that will be found eflicient in use, holding the blinds or shutters securely in either of its holding positions.

I claim as my improvementl. The combination of the leaf member having a perforated knuckle for receiving a pintle, with the pintle member comprising the half-soek ets, the pintle journaled on the outer end of the said half-sockets, and having the holding-plate rigid with the said pintle, the upper end of the said pintle being fitted to receive the knuckle of the said leaf member, the plunger bearing on the said holding-plate of the said pintle, and a spring within the half-sockets for acting on the said plunger.

2. The combination of the pintle member having the upwardly-projecting pintle and means for holding the said pintle in its several rotative positions, the upper end of the said pintle being of an irregular form in plan view, with the leaf member having a perforated hub or knuckle with the opening therethrough of an irregular form to correspond -with that of the said upper end of the said pintle.

3. In a hinge, the pintle member consisting of the half-sockets provided with spring and plunger recesses and pintle-lugs at their outer ends, the pintle journaled within the said pintle-lu gs and provided with a holding-plate'
